Crown I-Tech 4000 Amplifier
The Crown I-T4000 is a two-channel power amplifier designed for professional touring sound or fixed installation use. The unique hybrid design of the I-T4000 melds the high power, high output voltage, and clean transient response of a huge, heavy, old-school power amp, with onboard programmable DSP dynamics processing, computer networking capability, digital connectivity, and 24-bit/96 kHz A/D – D/A converters. All of which is packed into a lightweight 2 RU chassis of aluminum construction, weighing only 28 lbs. The rear panel of the I-T4000 is largely devoted to color-coded connector groups, all separately grouped and clearly labeled, which certainly simplifies the setup process.
Features:
- Global Power Supply – designed to deliver maximum power no matter where your schedule takes you
- Studio Quality Processing – integrated processing reduces DSP noise for a quieter overall system
- Peak voltage and RMS power limiting protects your speaker investment
- Front panel LCD provides diagnostics and preset selection to ensure fast and easy system setup
- Front panel lockout – ensures that tunings and presets are safely stored and protected from curious users
- Remote monitoring and control for complete system control anywhere in the venue
